Tiny OS Installation

Follow this page for Tiny OS installation.

Installation on Ubuntu

The installation procedure on the Tiny OS page only gives rpm's, which are meant for Redhat systems (or Redhat-similar systems). However, Ubuntu is a Debian-based system and therefore requires Debian-specific packages.
Nevertheless, the rpm's can still be used. You can follow the outline given on the Tiny OS installation page. You only need to convert rpm's into Debian packages. This can be done with the alien command:
sudo alien -d *.rpm

I installed the packages with Debian's package manager dpkg. The command is something like:
dpkg --install whatever.deb
It should also be possible to use the apt-get install command.

Stargate Programming

Programs

These programs can be copied onto the stargate with the scp command. It should be possible to run them just like this.
The source code for these programs is located on moses under /home/moses/tinyos-2.x/support/sdk/c.
The sources have to be cross-compiled for the ARM processor. The arm-gcc tools should be installed on moses.

Using the Programs

Serial Forwarder sf

The serial forwarder provides a bridge between the serial port and the network. Typically, on a stargate the serial port will connect to a micaz mote. The network on the other side could either be a connection via ethernet or just a connection on the local host.
Usage: sf port device speed
Example: sf 9002 /dev/tts/2 micaz

Serial Forwarder Send sfsend

This program demonstrates how packets can be sent out via the serial forwarder.
Example: sfsend IPADDRESS PORT 0x00 0xff 0xff 0x04 0x22 0x06 0x00 0x01 0x00 0xaa

This is a raw packet, which has to follow the packet specifications of the radio link. The given byte settings should work as an example for a broadcast packet. This is one aspect, which needs further investigation. Eventually we want to send our own information.

Mote Programming

Programs

Uploading the Programs

The TinyOS module can be loaded onto a mote either through the USB programming board or through the stargate. However, when doing it directly from the stargate, I have noticed that the uploading process blocks the serial interface. It's not possible to use the mote this way. Possibly (I'm just thinking about it, but I haven't tried it, yet), rebooting might solve the problem.
In any case, the two ways to upload the TinyOS program onto the mote are the following:

USB Programming Board under Linux

make micaz install mib510,/dev/ttyUSB0

Linux Programming

Programs

The following programs run so far only on a machine with regular Linux. It should be our goal to modify the source code in a way that they run on the Stargates. The source code can be found on moses under
/home/moses/tinyos-2.x/support/sdk/java

Java

Using the Programs

Java program Send

Example: java net.tinyos.tools.Send 00 ff ff 04 22 06 00 01 00 BB

Java program Listen

Communicate with a mote through serial interface (and USB programming board) using Listen:
java net.tinyos.tools.Listen -comm serial@/dev/ttyUSB1:micaz

How to listen to a serial forwarder:
java net.tinyos.tools.Listen -comm sf@IPADDRESS:9002
